When we think of a strong body, we often think of muscular arms and legs. But most experts agree that at the center of overall strength and fitness is the core, or torso, which includes the abdominals, back, and pelvis. Having a strong torso is very important for protecting against injury. It provides the body with a stable base in which to function. A strong core not only helps to support posture and protect the spine, it is also vital when we reach, lift, squat, kneel, walk, and run. In physical therapy, we often incorporate core exercises into rehab for shoulder, knee, and even ankle problems. A strong core will help prevent undue stress on the joints of the body and keep you balanced and stable.
